Hello,

I am trying to do a query after i add a feature to a layer and the shape and 
tile indexes are -1 so i can't get the shape that was queried. Below is my 
code in java, if you have any suggestions, please let me know.

thanks

            layerObj layer = map.getLayerByName( "towermark" );
            layer.setStatus( MapScript.MS_ON );

            pointObj myHouse = new pointObj();
            myHouse.setX( -104.06478597176886 );
            myHouse.setY( 38.46972580576644 );

            lineObj line = new lineObj();
            line.add( myHouse );
            shapeObj shape = new shapeObj( MapScript.MS_SHAPE_POINT );
            shape.add( line );
            layer.addFeature( shape );

            imageObj image = map.draw();

            pointObj queryPoint = new pointObj();
            queryPoint.setX( -104.06478597176886 );
            queryPoint.setY( 38.46972580576644 );
            int result = layer.queryByPoint( map, queryPoint, 
MapScript.MS_SINGLE, 10 );

            System.out.println( "result of query: " + result );
            System.out.println( "MS_SUCCESS: " + MapScript.MS_SUCCESS );
            System.out.println( "MS_FAILURE: " + MapScript.MS_FAILURE );

            resultCacheObj cache = layer.getResultcache();
            //prints 1
            System.out.println( "number of results: " + cache.getNumresults
() );

            resultCacheMemberObj resultObj = layer.getResult( 0 );
            System.out.println( "shape index: " + resultObj.getShapeindex() );
            System.out.println( "tile index: " + resultObj.getTileindex() );
            System.out.println( "Class index: " + resultObj.getClassindex() );

            shape = layer.getShape( resultObj.getTileindex(), 
resultObj.getShapeindex() );
            if ( shape != null )
            {
                System.out.println( "shape.getNumvalues(): " + 
shape.getNumvalues() );
            }
